"Cervical amyotrophy" due to spinal cord infarction

Case report on a patient who suffered on right-sided C6 root compression du e to prolapsed intervertebral disc C5/C6 mediolaterally. Directly after ope ration (Cloward) we found a severe pure motor deficit of the right hand. Cl inical investigation and neurophysiological data showed a nuclear type lesi on of segment C8/D1, but improvement of C6-lesion. T2-weighted MR-image sho wed a hyperintense spot in the lower cervical cord (C8/D1) in right-hand an terior horn area, We conclude, that this lower motor neuron lesion is cause d by spinal cord infarction in the anterior horn area, Intraoperative lesio ns of radicular artery feeding anterior spinal artery may cause infarction within the territory of the sulcocomissural artery.
